What version of this module are you using?

[x] 2.0.10 (Stable)
[x] 2.1.0-rc.13
[x] 2.1.0-rc.9

Please add a description for your issue:

I get an error for both 2.0.10 and 2.1.0-rc.13.4 but not 2.1.0-rc.9, where the SDK fails to build with the following error message:

...
Generating: ..../src/app/shared/sdk/models/Person.ts
readline.js:982
            throw err;
            ^

TypeError: ejs:5

    6| }
    7|
    8| export class <%- modelName %> implements <%- modelName %>Interface {

Cannot read property 'type' of undefined

I managed to pin down what triggers the error in my code: I extend the Loopback User model with a model called Person. If I add the line "hidden": ["username"] to the model configuration, building the SDK fails, otherwise not. If I hide email instead, building the SDK succeeds.
